You need more than just the fuel rail/venturi - the FI R1 uses a completely different head, ECM as well.

I am interested in doing the same. I have been keeping an eye out for a complete ECM, Harness, and throttle bodies. I do not think it would be a very hard install. The best thing to do is get as much info as possible. You would need a service manual and an ETM (electronics manual). If you really think about it a bike is no different than a sled. All of the sensors would be pretty much the same. You would have to use most of the sleds sub harnesses but you should be able to use all of the bikes engine management systems. There is no doubt that some things will have to be modified or revoved from the harnesess. The biggest thing is knowing how the whole thing should work. I have done quite a bit with fuel injection mods on vehicles. I have sorted through a lot of wires. Little things can sure piss you off. Like lakercr said the heads are different, but
that is not what I would be most concerned about. I have been stung big time by cam specs, Do your homework. As soon as I get the time I am going to look at doing it to mine.

I think you are going to run into more problems than you think. the entire fuel mapping and engine management system would have to be jerry rigged to work. I wish you the best of luck but it seems like alot of work for minimal gain. I would consider it if I was adding a turbo or something because fuel injection is easier to work with than carbs when Turbos are involved.

I do agree with you on the fuel mapping. There is no doubt that some programing would have to be done, And I agree that the performance gain may not be worth the money or effort. I think my first project will be with the rear suspension?? Redline???

I have already looked into doing this. There are several obstacles to overcome.
First, the R1 bike is a real downdraft style cylinder head. The RX1 is a down draft style head with sidedraft manifolds for the carbs. This means a severe mod is going to have to be done to the hood and airbox. Done properly, it will be a worthy gain but it will be extensive.
Secondly, I know for a fact that there are limits on how much you can adjust even fuel injection. I don't think the ECU will have the range of parameters to accomodate the intense cold, wintertime typical wehter we encounter on sleds. I mean I have ridden R1's and other FI motorcycles in 30 degree weather but minus 30 when the sled has already sat overnight outside is a totally different thing requiring a range of adjustability that the ECU does not have.
Thirdly, the ignition system on the sled versus the bike are not the same. The ENTIRE ignition system would need to be installed from the bike.
I also think (but am not certain on this one) that the extreme cold temperatures are not going to treat the current electronics too well and might pose problems with their working.
I love FI and tune FI equipped bikes almost everyday during the motorcycling season in our shop. FI is definately the way to go but some obstacles will need to be dealt with and these obstacles might prove to be quite the challenge.
I love the idea though.
